Abstract: The parameterized dynamic model of the impact corapaotor is.made based on the classioal Hamilton's canonical equations, It is applied on the YCT-25 impact compactor. The motion characters after the simulation are got and they are in accord with the experiments data .The results oan offer some reference theory to the design and manufacture of the machine and they are also useful to the optimum of the machine.
